To 'all whom it may concern:

Be it known that I, CoNRAn'HUBnRT, a citizen of the Unit-ed States, residing at the city of New York, in the county of New York and State vof New York, have invented a certain newand useful Improvement in Closures for Vessels, of which the following is a specification, reference being hadtherein to the accompanying drawings, forming part thereof.

My invention relates generally to closures for vessels and relates particularly to closures for bottles or flasks which in use are exposed to jars and vibrations, for example, vessels or containing liquid food and beverages to be c arried on rapidly moving vehicles, such as automobiles. ll

4The principal objects of my inventionv are i to prevent the closure of such a vessel from becoming loosened by jars and vibrations, and to provideaclosure having a neat and finished appearance. p

There are also other objects and advan taveo'us features which will appear from the fol owing description.

Difficulty has been found in providing a.

which will Iremain tight when the vessels are subjected to vibration, especially in use on automobiles. This difficulty has been particularly .acute in reference to heat insulating vessels that are adapted to preserve their contents in'a hot or in a cold periods, as the slig-htest loosening .of the closure permits the passage of heat, and when the contents are hot there iden-internal pressure which 'tends to open the closure. My invention is directed to overcon'iing these difficulties, and to these ends my invention includes a stopper fitting into the neck or inouth of the vessel and provided outwardly with two telescoping niembers within which is a thrust spring adapted to act throughout va considerable range oll movement, the Whole forining a closure which is adapted to cooperate with the usual outer cap of the Vessel.

1 will now describe my invention with reference to the accompanying drawings and will thereafter point out my invention in claims. l

In the embodiment of my invention illustrated in the drawings a tapered stopper 1 of yielding resilient material, for example, of cork, as indicated in the drawings, is secured at its u lper and larger end in a metal annulus '2 which surrounds and firmly grips the upper portion of the stop er 1, in manufacture the tapered stopper eing forced down through the annulus. The annulus 2 extends above tlie top of the stop er 1 and is enlarged into a flange portion orininr annular inner 'and outer shoulders, the inner shoulder being substantially flush with the top of the stopper 1. An annular metal socket 3 is provided at its bottom with an enlarged ortion or flange portion telescoping over t e enlarged 2 and clenched or spun down under the outer getlier the socket and the annulus. The socket 5 is contracted above the. annulus 2 to forni an internal annular shoulder oposed to the internal shoulder on the annuus 2. [a disk el of any suitable material harder and Aiiriiier than the stopper 1, for example, i'ndurated fiber or compressed papel', is seated in the annular groove formed between the shouldersy of the annulus 2 and the socket 3 immediately above the sto )per l, and a metal washer 5 ovei'lies the disfc 4 and fits in the contracted portion of the socket 3. The disk 4 and the washer 5 are secured to the stopper i, the securing means being shown as a screw'. The disk 4, because of the fact that it is seated in the groove formed by the peripheral enlargements of the almuportion of the annulus vso his and the socket, greatly assists in holding the Stopper in place 4iii the annulus.

A cup-sha )ed metal cap 7 telescopes in the socket 3 and is retained therein by coactilifr annular flanges Aat the top of the socket and at the bottom of the cap 7, as shown the drawings, and llie teleseo )ing movement is limited by such flanges and by the washer 5, the extent of such telesco )ing inovemei t however, being of considerable range, as may be seen in Fig. l. The cap or cup 7 and the stopper l are constantly thrust away from each other, 'the cap 7 being thrust toward its extended position in iclation to the annular socket 3, by a coiled thrust spring 8 located within the cap 7 anil socket 3 an acting between the top of tle cap 7 and the washer 5.

The sprin 8 has. some initial tension to fully serve its function e stop er 1 from vworking out of the mouth or neell of the vessel.V The peri heral enlargement provides a firm fin-- er old in inserting or removing the closure om the vessel. Inusin the closure the stopper portion 1 is adapte to be inserted into the mouth of thfe vessel to a variable extent, that is, to a greater or less extent or degree, in the same. manner in this respect as an ordina cork; and should -the sto per portion ecome somewhat permanent compressed or reduced in diameter br long continued use'it ma then be inserte to a greater extent to Vessels of t e. classr to which the closure of my invention is intended:v and adapted to be 'applied are provided, in addition to the corks or other closures proper, withouter cover-caps which are detachably retained in any convenient manner in fixed position over the 4mouths of the vessels, such a cover-cap sheath for the vessel. The closure of m invention is adapted to be retained in a uidthe vessel by sucha cover-cap, and is so the mouth or neck of the vessel, and such air-tight and fluid-tight iit is maintained in spite of jolts, jars or vibrations to which the an ordinary cork to work out and become In the drawings the closure oi' my invention `is shown as applied to a heat. insulating vessel having spaced walls inelosing a vacuumjacket, as well known in the art, the pppwer portion only of such vessel being shown. his vessel is shown as (provided witha proing an outer metal sheath 9. The sheath 9, near its upper edge, is provided with diametrically opposite lugs- 10, for retaining in place a metal cover-cap 11i-Which is provided at its lower edge wit ba onet slots, as shown most clearly in Fig. 2, Ivor receiving such lugs.

In use it is only necessary to insert the closure into the vessel until it is tight, in the same manner that an ordinary cor would be ea 11 is applied to the vessel its closed top wi l press r ownward or inward on the inner cap or eu 7 and the thrust spring 8 will firmly an( securelyjhold the stopper 1` in its 8 is centered relatively to the,-

When the protective and c osure-retaining cover-cap 11' is removed, the closure v'presents a neat, attractive'and nished apearance, and maintains the seal d condition ofthe vessel until the closure is intentionally removed, and the closure maj)T beremoved and inserted in the same manner as an ordinary cork.

' 1n the modification ofmy invention illustrated in Figs. 4 and 5 a tapered stopper 12, of yielding resilient material similar to the sto per 1, is provided and is ixed at its upper an arger end, .with cement or in any suitable manner, in an annular socket 13 yo firmer and harder material, for example,

hard rubber,- the. socket 13 beingl provided g5 with a shculder'for assisting in fixing) stopper 1. A washer 14, which may any s uitablematerial, is shown as interposed between the shoulder of the'socket 413 'and the top of the' stopper 12. A metal cap 15, similar to the cap 7, telescopes in thesocket 13 and is retained therein by enacting annular flanges at the top of the socket 13 and at the bottom o'r' the. cap 15 the telescuping movement ofthe cap 15 being limite by such flanges and by the Washer 14. The ca 15 and the stop er 12 are constantly pressed apart or pushe away from each other by a coiled thrust spring 16 within the cap 15 and 'socket 13 and acting-between the topof the cap 15 and the vWasher- 14, The annular socket 13 is provided-outwardly around its circumference or periphery with milling (Fig. 5) which providesl a secure finger hold in inserting or removing the closure from the vessel.

, The mannerof-operation' of the modified construction shown in Figs. 4 and 5 is substantially the same as of the construction shown in Figs. 1 and 3, and in fact this modied closure could be substituted for the the cap acting between the cap and t e stopthe' e of per to press the cap away from the stopper.
